My electric bills have gone down about 20%. The air quality in my house is much, much improved. I've been really impressed with Dayton's Pest Control because they've always done exactly what they said they were going to do, and they show up when they say they're going to show up.
We no longer have water. When it does rain, the pipes that they put in are collecting the water and pumping it out immediately, which has eliminated the dampness and the musty air, and any kind of mold problems.
